Consumer surplus=0.5(6600-2200)(8800)=$19360000
Producer surplus= 0.5(2200)(8800)=$9680000
When Price= $1800
Quantity demanded= 10000
Quantity Supplied= 6400
Shortage=10000-6400= 3600
New consumer surplus=0.5(6600-3400)*6400=$10240000
New Producer surplus=0.5(6400)(1600)= $5120000
Deadweight loss= 0.5(3400-1600)(8800-6400)= $2160000
After Black market, Highest rent=$3400
New producer surplus= (3400-1600)(6400)+0.5(6400)(1600)= $1152000+$5120000=$6272000
